Oligarchic majority rules bring the voice but no vote principle into effect. We prove characterizations of the oligarchic majority rules for both fixed and unrestricted societies and a binary agenda. This is a general class of rules that includes the simple majority rule as well as dictatorships. Suitable sets of axioms identify a subsociety whose members have voice but no vote, and valid votes are aggregated by the majority rule.
